I’m not a subscriber. I do enjoy Game of Thrones, but I’m more than willing to wait for the blu-ray or iTunes release, even though I know it puts me a year behind. I’ve read the books, so it’s not like I’m going to be hit with huge spoilers by waiting. Nothing else on HBO seems worth it to me - original programming (other than GoT) doesn’t appeal, and the movies they carry are the same ones I didn’t want to watch in the theater in the first place.
Did you know that Youtube has some pretty good full length movies, free!
